Compressible Euler equations with time-dependent damping in the critical regularity setting: global well-posedness and strong relaxation limit

Timothée Crin-Barat, Xinghong Pan, Ling-Yun Shou +1

We investigate the relaxation problem and the diffusion phenomenon for the compressible Euler system with a time-dependent damping coefficient of the form in $…

Global convergence rates in the relaxation limits for the compressible Euler and Euler-Maxwell systems in Sobolev spaces

Timothée Crin-Barat, Yue-Jun Peng, Ling-Yun Shou

We study two relaxation problems in the class of partially dissipative hyperbolic systems: the compressible Euler system and the compressible Euler-Maxwell system. In classical Sob…

Strong relaxation limit and uniform time asymptotics of the Jin-Xin model in the framework

Timothée Crin-Barat, Ling-Yun Shou, Jianzhong Zhang

We investigate the time-asymptotic stability of the Jin-Xin model and its diffusive relaxation limit toward viscous conservation laws in for . First, we est…

Large-Time Asymptotics for Hyperbolic Systems with Non-Symmetric Relaxation: An Algorithmic Approach

Timothée Crin-Barat, Lorenzo Liverani, Ling-Yun Shou +1

We study the stability of one-dimensional linear hyperbolic systems with non-symmetric relaxation. Introducing a new frequency-dependent Kalman stability condition, we prove an abs…

Global existence and optimal time-decay rates of the compressible Navier-Stokes-Euler system

Hai-Liang Li, Ling-Yun Shou

In this paper, we consider the Cauchy problem of the multi-dimensional compressible Navier-Stokes-Euler system for two-phase flow motion, which consists of the isentropic compressi…

A new characterization of the dissipation structure and the relaxation limit for the compressible Euler-Maxwell system

Timothée Crin-Barat, Yue-Jun Peng, Ling-Yun Shou +1

We investigate the three-dimensional compressible Euler-Maxwell system, a model for simulating the transport of electrons interacting with propagating electromagnetic waves in semi…
